AbstractObjective: To evaluate the early and mid-term results of the first 100 elective endovascular repairs for abdominal aortic aneurysms. Design: Retrospective analysis of prospectively collected data. Setting: University teaching hospital, Hong Kong. Patients: The first 100 patients with infrarenal abdominal aortic aneurysms who underwent elective endovascular repair. Main outcome measures: Peri-operative data, mortality and morbidities as well as the follow-up details were recorded. Cumulative data on endoleaks, clinical failures, secondary procedures, and survival were evaluated with Kaplan-Meier analyses. Results: There were 85 men and 15 women, with a mean age of 75 (range, 50-90) years. Failed implantations due to access difficulty occurred in two patients during the same period, giving a technical success rate of 98%. The mean aneurysm diameter was 6.2 cm. Access site injury requiring repair occurred in four (4%) of the patients, while wound problems were the most common complications (11%). The median hospital stay was 6 days, and there were two hospital deaths, giving a hospital mortality rate of 2%. During a mean followup of 36 (standard deviation, 24) months, there were three aneurysmal ruptures and four elective open conversions, with only one aneurysm-related death after hospital discharge. At 3 years, the cumulative rates of freedom from any endoleak, freedom from primary failure, freedom from secondary failure, freedom from secondary procedures, and survival were 60%, 84%, 89%, 88%, and 78%, respectively. Conclusions: The early and mid-term results of elective endovascular repair for abdominal aortic aneurysms appear promising. The procedure is effective in preventing aneurysm-related death in the mid-term. Nevertheless, the importance of constant surveillance cannot be over-emphasised, as clinical failures and ruptures are still a concern.
